CARBON SHEET ARRANGEMENT FOR USE WITH CONTINUOUS STATIONERY Filed Aug. 5, 1947 Patented Mar. 18, 1952 .CARBON SHEET ARRANGEMENT FOR USE WITH CONTINUOUS STATIONERY John William Randall, Hemel Hempstead, England, assignor to John Dickinson & Co. Limited, Hemel Hempstead, England, a British company Application August 5, 1947, Serial No. 766,291 In Great Britain June 14, 1945 Section 1, Public Law 690, August 8, 1946 Patent expires June 14, 1965 4 Claims. 1

This invention relates to an improved carbon sheet arrangement for use with continuous stationery but has particular reference to an improved carbon sheet arrangement for use with suitable apparatus .for feeding carbon interleaved typescript ina typewriter or like machine adapted to type or print webs of continuous stationery whereby the pile, reels or other'known formations of the said continuous stationery may be in a defined position relative to the typewriter or like machine, the said continuous stationery being automatically longitudinally displaced relative to the carriage by the said carbon sheet arrangement.

To provide correct alignment of webs previous to entering the said typewriter or like machine, and for the purpose of enabling the said continuous stationery to be displaced longitudinally, I provide an attachment comprising a thin flexible smoothing sheet to which may be affixed at one end thereof a support strip for engagement with the carbon sheet holder, and at the opposite end thereof a guide which affords the necessary control of the said webs of continuous stationery.

The carbon sheet holder is constructed from a single sheet of suitable material, of substantially rectangular form, folded lengthwise, preferably about a central axis, to form a pocket and suitably shaped to provide the necessary features as hereinafter described.

'A slot is provided at the lower end of the said pocket through which to pass the interleaved carbon sheets and continuous stationery, the said slot being of such dimensions as to ensure complete control of the webs.

In order to facilitate interleaving the continuous stationerywebs with the carbon sheets, I have found it desirable to remove a portion of the front wall of the carbon sheet holder. This cut away portion should be of slightly greater width than the continuous stationery.

The said carbon sheets are mounted at their top edges on stiffening strips of convenient width and shape, and are assembled between the fold of the said carbon sheet holder which is then secured by suitable means to retain the said stiffener strips in position. It will be appreciated that by this means varying numbers and sizes of carbon sheets may be assembled in the aforementioned holder.

In the preferred form, the holder will be provided with side extensions adapted to engage slots in the carbon sheet holder support strip.

It will also be understood that other constructions may be applied which would come within the scope of the invention.

The carbon :sheet holder support and the guide member are made wide in order to accommodate varying widths of stationery.

In order that the application in use of this invention may be more fully understood, I will now describe the method of use of a preferred form with particular reference tothe accompanying drawings.

' Fig. l is front elevation showing the carbon sheet holder inserted in the support strip.

Fig. 2 is side elevation showing the carbon sheet arrangement attached to any suitable apparatus for feeding carbon interleaved typescript.

Fig. 3 is a detail of the carbon sheet holder ible smoothing sheet I an adjustable paper guide 3 and a carbon holder support strip fitted with adjustable clips 2, is attached to any suitable apparatus for feeding carbon interleaved relatively continuous typescript through typewriters or the like, and the webs are threaded through the guide 3 longitudinally parallel to the smoothing sheet I and then interlaced through the stiffening strips 6 of the carbon sheet holder, Fig. 4, the said carbon sheet holder being gripped with the adjustable clips of the support strip 2. Then the webs of continuous stationery are passed between the feed rollers and the platen of the typewriting machine by way of the apparatus attached to the typewriter for use in the usual manner.

The guide 3 is a single piece of material extending transverse of the sheet I and attached thereto at the far end of the sheet I, and it has folded over ends which do not meet, forming a loose clip, through which the webs are threaded by folding them longitudinally, placing them in the guide, and then flattening them therein so that they slide therethrough freely, but are held aligned at their edges by the guide? The guide 3 and the smoothing sheet I will then operate by holding the webs of continuous stationery firmly and in true alignment to facilitate the smooth operation of the webs through the typewriter when being worked by the operator of the typewriting machine, also permitting the webs to be reversed along the same alignment to allow the carbon sheets to be cleared from the first set of forms when they are ready for severance, and thus enabling the carbon sheets to interleave the succeeding set of forms on the Webs in an easy and smooth manner.

The carbon sheet holder shown in Figs. 3 and 4 is constructed from a single sheet of suitable material 4 folded along line 1 to form a pocket into which are afiixed carbon sheet stiffeners 6 to which are secured the carbon sheets 5. A slot 8 is provided at the fold of the pocket to permit passage of carbon sheets and relatively continuous stationery.

I claim:

1. A manifolding attachment for use with multiple sheeted webs of relatively continuous stationery on a manifolding machine having a rearwardly projecting support from which sheets may be fed to and around the platen of the manifolding machine, the attachment comprising a fiexible smoothing sheet extending around the end of the machine support, a web guide at the far end of said sheet, from the platen, through which the continuous stationery is threaded, a support strip at the near end of said sheet, a carbon sheet holder formed of a single sheet folded transversely upon itself and having arms extending transversely from its open side held by said support strip, the holder having a pocket in its open side, one or more carbon sheets having strips across one end and projecting from the edges thereof, said carbon sheets being threaded through said pocket and held by said projecting strips from pulling therethrough, the continuous webs likewise being threaded through said pocket with sheets thereof on each side of said carbon sheets, whereby the webs and carbon sheets may be fed through the manifolding machine up to the holder and upon reversing the feeding movement, the carbon sheets and carbon sheet holder may be held stationary to permit fresh portions of the webs to be advanced into interleaved relation with the carbon sheets.

2. The manifolding attachment of claim 1 in which the carbon sheet holder is detachably held by the support strip.

3. The manifolding attachment of claim 1 in which the flexible smoothing sheet carries therewith around the machine projecting support the multiple sheeted webs and smooths them, for their future imprinting in the manifolding machine.

4. The manifolding attachment of claim 1 in which the web guide is open on one side at the center, whereby the webs may be threaded thereinto between the web ends, by folding the webs and then straightening them within the guide.
